# (Originais Teachy 2023) - Question Medium of Physics

A car initially travels at 20 m/s, maintaining a constant speed on the highway, going from point A to point B, which is 2000 meters away from A. On the return from point B to point A, the car follows the same trajectory, but with a speed of 30 m/s. Considering that the trajectory from point A to point B is straight and can be represented by an Aristotelian line, what was the average speed of the car during the entire round trip (A-B-A)?
a.
24 m/s
b.
20 m/s
c.
30 m/s
d.
22 m/s
e.
25 m/s
